All the knockout matches should be automatically updated but there is a bug for the match between Belgium and Japan. Here is the quick fix:-

Go to AdapterListKOMatches.java & MatchDetailActivity.java and change all the below statements:

1) < 32 change to <=32

2) > 32 change to >= 32

Example:-

if (p.home_team.getClass().equals(String.class)) {
view.name1.setText(p.home_team.toString());
} else {
if (Integer.valueOf(p.home_team.toString()) <= 32) {
view.name1.setText(Tools.getTeam(Integer.valueOf(p.home_team.toString()) - 1).name);
Tools.displayImageRound(ctx, view.image1, Tools.getDrawable(ctx, Tools.getTeam(Integer.valueOf(p.home_team.toString()) - 1).iso2));
} else
view.name1.setText(p.home_team.toString());
}

Please perform the changes on both the admin and client apps.

Sorry for the inconvenience caused. Thank you.
